wider than anterior margin. Hind lobe with the lateral margins 

 fairly straight, but widely divergent, posterior margin more than 

 twice as wide as anterior margin of pronotum; anterior half 

 medially carinate. Scutellum longer than wide, depressed 

 basally and at the sides, coarsely punctured on anterior margin 

 of disk and on the sides. Clavus with three or four irregular 

 rows of punctures. Corium with two rows internally and the 

 external margin of the apical half, closely punctured, the rest 

 smooth and polished. Membrane with strong, curved veins. 

 Fore femora incrassate, with three or four longer spines and 

 several shorter ones; tibiae curved. First segment of hind tarsi 

 nearly as long as the others together. 



This has puzzled me considerably. Although there is not a 

 proper collar, I would place it in the Myodochini. There is some 

 affinity to Dieuches Stal, but the anterior lobe of the pronotum 

 is entirely rounded. It is perhaps nearest to Eucosmelus Bergroth, 

 but the head is much narrower and more elongate, and the 

 pronotum is distinctly divergent laterally.

Black; labium, antennae, apex of tylus, etc., yellowish-testa- 

 ceous, more or less sordid; " collar," posterior lobe of pronotum 

 (both strongly punctured with blackish-brown), an elongate V on 

 disk of scutellum, corium, etc., brownish-yellow. Clavus almost 

 entirely dark fuscous. Corium with a large blackish spot at 

 inner apical angle, the rest of the smooth part brown, punctures 

 blackish-brown. Membrane dark fuliginous, veins pale and 

 sordid, apex yellowish. Legs brownish-yellow, fore femora 

 stained and spotted with dark brown, apex of fore tibiae, etc., 

 dark fuscous. Anterior lobe of pronotum twice as long as 

 posterior lobe, medially. Fore femora strongly incrassate. 

 Length, $ 10 mill.

46. I. oceanicus, sp.nov. 



Very similar to the last, but smaller; and the anterior lobe of 

 the pronotum barely one-half longer than the posterior lobe.
